Structure of DTF PET Film
DTF film is produced on the base layer of the PET material, coated with release layer and ink-absorption layer. High quality film adds back coating to realize anti-static electricity and anti-adhesion continuous treatment.
For example, DTF film from Sublistar owns 5 coating process, including anti-blocking treatment, anti-static treatments, PET substrate, matte coating, release coating, ink receptive coating.
How to Better Use the DTF Film? 4 Tips to Know
Though choosing the premium quality DTF film can significantly improve the printing quality, knowing following 4 tips can make DTF printing even better:
- Differentiate the printing surface – The side with ink-absorption is printing side;
- Dry for 40-90 seconds after printing(set suitable temperature according to the performance of hot melt powder);
- Work with hot melt powder with a particle size 60-80μ can realize instant peeling; particle size 100-150 |J dtf powder is suitable for cold peeling; particle size higher than 150μsuggests cold peeling;
- Store DTF film in dry environment and pay attention to moisture -proof.
Where DTF film can be applied? Substrate (Applications) of DTF film
DTF film is widely applied to various fabrics, no matter dark or light like cotton, nylon, polyester, canvas, denim and more. In fact, DTF film can be applied to almost unlimited types of fabric.

What are the Types of DTF Film? By Different Classifications.
Before knowing how to choose the most suitable DTF film for printing business, getting an idea about the different types of DTF film is the first thing to know.
Though most known types of DTF film are hot peel and cold peel, that’s only one of the way to classify, there are more types named from different perspective.
By Coating Process
According to coating process, DTF film can be classified into single side coating film and double-side coating film. At the beginning development period of DTF printing, single side coating film is popular. However, at that time, most machines were not mature and had the problems of sliding dislocation. Hence double-side coating film(adding coating in the back) was designed to prevent sliding.
By Releae Process
According to release process, DTF film can be classified into hot peel film and cold peel film(know the difference between cold peel and hot peel film). Cold peel film is not able to peel the backing until the film cool down after heat pressing. However, the backing of the hot peel film will be torn off soon after heat pressing due to the wax content.
By Visual Effect
According to visual effect, DTF film can be classified into reflective colorful film, laser film, luminous film, temperature change film, shining film.
Reflective colorful film could reflect light, creating unique visual impact and making your design eye-catching.
Laser film is able to present laser under light. In the dark environment, images printed by luminous film will shine and show green light.
Temperature change film will make pattern show different effect under different temperature. When the temperature rises, designs will become brighter. When it decreases, designs will become dark.
Shining film will bring patterns shinning impact.
How to Choose Best DTF Film? 6 Key Factors
As there are various types of DTF film in the market, usually, consider the following 6 factors to choose DTF film makes no wrong choice:
- Ink-absorption capacity
- Coating layer
- Powder shaking effect
- Release effect
- Storage capacity
- High temperature resistance
Poor ink-absorption capacity may cause that white and color ink mix or even flow on the films. So it is important to choose film with high ink-absorption coating.
DTF film is base film coated with special coating. If the coating is uneven or mixed with impurities, it will directly affect the printing effect. Thence, it is necessary to observe whether the surface coating is even and delicate.
Powder Shaking Effect
There will be some powder on the edges of the pattern after shaking if the film has bad powder shaking ability. That will make your transfer dirty. Edges of film with good powder shaking effect will be clean without residue. You can use some samples to test the powder shaking effect before you decide to purchase.
Qualified DTF film is easy to tear off after pressing. Bad DTF film is difficult to tear off or peeling the backing will damage the patterns. Testing the release effect is also necessary before ordering.
After period of time, oil water on the DTF film may come out even they are kept in their original packing. Good DTF film will always keep clean in the surface even if it is not used for a long time.
High Temperature Resistance
After printing and powder shaking, DTF film needs to enter high-temperature oven for crying. Hot melt powder will begin to melt when the temperature is over 80℃, so DTF film must withstand high temperature. If the film does not become yellow and wrinkle under the test temperatue of 120℃, it can be identified as good quality.
